To all whom/ it ntwy concern:

Be it known that I, Hnunr S. .DUIRAND, a citizen'o'l the United States, and a. resident of Rochester, in the county of Monroe and. State of New York, have invented certain new and useful Improvements in .ll eaters, of which the following is a specification.

This invention relates to heaters, and has for its object to provide a burner, adapted to the consumption of k0IOS(-\l16--0ll, that is sim' ple in construction and econon'iical in operation.

in the drawings, Figure 1 is a side elevation of the burner and its attachn'ients. Fig. 2 is an enlarged view of a portion of a section on the line 4 4 of Fig. i. Fig. 3 is :in end view oi the burner and attachments represented in l i I, and Fig. 4 is a section on the line 4' of lig. l.

A. represents a tube closed at one end A. The tube is re 'iresented as hexagonal, although it is not essential that it should have that 'l'orni, and its other end A s preferably la-rod. The three uppermost surfaces of the tube A are perforated thrlnighmit their length and lu'cadth, as represented in Fig. 1. These perforations are circular in crosssoction, and within each is driven a square plug (.L, that partly :lills the perforation. These plugs close, respectively, the perforations except for the tour narrow slits 0, around each plug, which are the burner-ori'lices through which the gas is discharged to the flame. The shape of these pl ugs is essential only so far as it reduces the perforations to slits of such size and shape that they will have the advantages of the slits a, and are easy to manulacturc.

T he oil is introduced through the pipe B, which leads to a reservoir (not shown in the drawings) wherein the supply of oil is kept under sullicient pressure to force it through the pin-valve to which the reservoir is connectod by 8, system of pipes.

which. the pipe B is screwed, and the pipe B which is screwed into the other end of the pipe B. The pipe B is represented as somewhat larger than the pipes B and B and is intended to be filled with steel shavings or other material for equalizing the pressure of the oil. Other suitable means to this end may be employed, if desired but this equalizing means is not essential to the operation of the burner. Brackets b b, Whiclrmay be cast upon the pipe B, orother means adapted Such conned, tion 18 represented by the pipe B, intoto be connected with the tube A hold the pipe B above that part of said tube that is perforated, es described above.

The pipe B passes around the tube A and is turned upwardly, so that the valve C upon its end brought in front 01'' the flaring end.

' A of the tube A at about its central point.

A bracket 7) upon the end Al of thetube A supports the end of the pipe Beneath the tube A the tube .8 passes 'througl' the upper part of a heater D, which is attached to the under side of the tube A, by brackets (Z (Z, cast upon the tube D or otherwise secured to it. The outer end 1) of the heater .l) closed; but its front end l)" is open. The upper part of the tube l) por forated, as d.

An oil-tank E with an atomizing ltt-tliLCilr nient E of the well-known construction and a pipe it", from which air is Forced through. the atomizer, are shown in iigs. 1 and 3 located in front ol' the heats The burner is operated and lighted in the following manner: Compressed air is adc mitted to the atomizer through the pipe E which operates to draw oil from. the tank l9 and to spray it from the atomizer Efin the usual way. The spray is ignited, and the [lame under pressure ol E" enters the end B of the heater. The ilanie heats that part of the pipe B that is within said pipe 1) and passing through the perforations d h rats also the tube A. When the pipe B has been heated to such. it degree that the oil contained in it will vaporize, the pin-valve C is opened. The pressure on the oil in tl1= supi ily tzink, (not shown,) with which the pipe B connects, will force the vapor that is discharged from the valve G into the tube A. A. supply of air will be ourried into the end A of the pipe with the va-- por that will insure complete combustion.

The vapor thus mixed with air is ignited as it escapes through the slits a in the tube A and will heat surrounding surfaces. This burner will also heat the pipe B, which lies above it, thereby vaporizing the oil contained therein. When the pipe B has been heated Sulliciently for that to take place, it is no longer necessary to use the atomizer E and the heater D, for the burner itself is adequate for vaporizing the oil-supply. Thus the atomizer and the heater are only used to start the burner-in operation, and when that has been done the burner is adapted to reduce the oil to proper'forin for consumption and is sothe air from the pipe cordingly complete in itself. It is also obvious that in place of the atomizer and heater 'herein. shown and described other such de- Vith the vapor that discl'iarged from thevalve C a certain amount of oil may also be discharged into the tube A and a part of the vapor may condense within the tube A. To prevent such oil from dripping out from said tube A, a dam l" is placed across the lower part of the opening of the end A of the tube A, and, such. oil is conducted from said tube A to areceptaele by some suitable means, by the pipe G. It has been shown that While the heater 1) is vaporizing the oilin the ipe B it is also heating the burner-tube A. In this way the temperature of the said tube A is raised till it is sufficient to maintain the gas injected into it from the valve 0 at lighting temperature. The peculiar arrangement of the. buri'ier-tube and supply-pipe with referei'ice to each other make it possible to heat both parts at the same time. The arched form of the tube A and the use of series of burner-holes at different horizontal levels serve to maintain the heat of the burner-body, and being without air-spaces between the burner-holes improve the quality of the flame and give high eflicienoy.

A wirergauze If is inserted within the tube A beneath those of its surfaces that are perorated (see Fig. 3) and acts to prevent the ilames from entering said tube through the perforations a and'reaching the pin-valve C, as they otherwise might.

What I claim is 1.. The combination of a horizontal burnertube closed at one end and perforated blll'()1ll1fillt upper part, an oil-supply pipe extending along the upper perforated portion of the lmrnertube and having a lower portion, a valved disclurrge-jet for the supply pipe at the open end of the burner-tube, and a foraminatcd heater-tube extending along the under side of the non-perforated portion of the burner-tube and also along said lower portion of the oi l-supply pipe to heat the pipe and tube sinniltaneously, and separate means for (.Iischa'rging oil into said heater.

* 2. The combination of a luirner-tube, having one end closed, and perforated through out its upper part; a valve adapted to control the discharge of vapor into the open end of said burner.-tube; an oil supply for said valve, a part of said pipe being located above the perforations in said burner-tube, and a part thereof beneath said tube; means for supporting said supply-pipe above and beneath d burner-tube and a heater adapted to vaporize oil contained in said supply-pipe and at the same time to heat said burnertube; substantially as shown and described.

3. The combination of the burner-tube A, having one end closed, the flared end A and perforations a throughout its upper part; the valve C adapted to discharge vapor into said lmrnentube; the pipe B connected to an oil-supply, and the pipe 13'' connecting said pipe 13 with said valve C, said pipe B being supported above said burner-tube, and the pipe beneath it; the tube D attached to said burner-tube having the perforations (1, one end closed, and, the other open and inclosing the pipe B; and the atomizer E arranged to spray vapor into the perforated tube D; substantially as shown and described.

4. The combination with a burnertube perforated along its upper portion and closed at one end and a su 'iply-pipe extending along the burner-tube and provided with a valved discharge at the open end of the tube, ofa heater-tube surrounding the supply-tube and perforated along its upper side to heat the burner-tube and an atomizer discharging into the heater-tube.

5. The combination with a burner-tube closed at one end. and having perforations along its upper portion, plugs within'said perforations; the plugs and apertures being shaped to form slits between. them, wiregauze along the inner side of the perforated portion of the tube, an oil-supply having a valved discharge at the open end of the tube,

a tubular heater perforated along one side to heat both the burner-tube and oilsupply pipe and an atomizer discharging into the open end of the said heater.

6. A burne comprising a burner-tube closed at one end and perforated along its upper portion, an oilsuppl v pipe having an enlarged member extending along the upper perforated portion of the tube and a lower smaller member extending along the lower side of the tube and provided at the front open end thereof with a valved jet to discharge into the tube, a l'ieater-tube inclosing said lower pipe member and perforated along its upper portion and an atomizer discharging into the heater-tube.
